Application filed. March 6, 1918. Serial No. 220,843.

To all whom it may concern:

Be it known that I, J AM'ES FLUKER, a subject of the King of Great Britain and Ireland, residing at The Manor, Feltham, Middlesex, England, have invented certain new and useful Improvements Relating to Fire- Extinguishers, of which the following is a specification. I

This invention relates to fire extinguishers.

In fire extinguishers it has before been proposed to mount the extinguisher casing in its reversed position with the outlet end of the discharge pipe at the lower end and with the inner end of the discharge pipe above the level of the extinguishing liquid, so that by such means the air space above the liquid in that position communicates with the atmosphere through the discharge pipe and thus the discharge pipe serves when the extinguisher is not in use to allow of the outlet of the expanded air or gas when the extinguisher is exposed to heat, and is not in communication with the liquid.

The present invention has for its object to prevent the discharge of liquid from within the casing of such extinguishers through the discharge pipe, when the easing is subjected to movement as for example when mounted on vessels, motor vehicles or trains.

According to the invention a small casing is mounted at the inwardly protruding end of the main part of the discharge pipe, while at the opposite end of the small casing a short length of pipe protrudes into the casing.

The invention is illustrated in the accompanying drawings in which Figure 1 is an elevation partly in section of a fire extinguisher constructed according to the invention, and

Fig. 2 is a section on the line a0y Fig. 1.

Fig. 3 is a detail vertical section through the axes of the parts a and 0.

According to the invention the inwardly protruding end of the discharge pipe (1, (that is the upper end with reference to the position of the casing out of use represented in Fig. 1) has mounted upon it a small in closing casing 71 within the upper part of the extinguisher casing and a short open ended pipe 0 extends also within the small casing in an opposite direction from the upper or rear end while drawing holes (Z d are provided at the bottom of this small casing Z) so that by such means the upper or inwardly protruding end of the discharge pipe a is completely inclosed by the casing b which covers that end of the discharge pipeso that the liquid cannot, as the result of movement or splashing, pass down the discharge pipe in the position in which it is maintained when out of use, while moreover by so providing the small casing it serves as a reservoir of liquid when the casing is held in the position of use and thus the fitting or attachmentafiords no hindrance to the effective use of the extinguisher but on the contrary is of assistance in 'maintaining a quantity of liquid at the inner end of the discharge pipe notwithstanding that the level of the extinguishing liquid falls below the casing,

It will be understood that the casing a is provided with a hole at one end through which the inner end of the discharge pipe a may pass and be held therein with a tight joint or fit, while similarly the short open ended pipe 0 is passed through a second hole in the casing a at the opposite end but out of line with the hole through which the end of the discharge pipe passes, and the open ended pipe c-is passed through this second hole and held therein with a tight joint or fit. By such means the casing Z) is firmly carried upon the end of the discharge pipe and the pipe 0 is firmly held in the casing b.

It will be understood that the short pipe 0 may extend to the central cavity usually formed at the rear end of the extinguisher casing and serves as a means by which liquid may pass to the small casing or fitting on the extinguisher casing being brought into its position for use.

I claim:

1. In a fire extinguisher, in combination, an invertible container for holding gas generating chemicals, a discharge pipe extending through the container nearly to the bottom, a casing surrounding and inclosing the end of said pipe, and a second pipe extending within the casing from the bottom of the container past the end of the first pipe.

2. In a fire extinguisher, in combination,

an invertible container for holding gas gen extending past the end of the first pipe crating chemicals, a discharge pipe extendnearly to the top of the casing, whereby ing through the container nearly to its lower splashing and premature generation of gas 10 end, a tight casing inclosing the bottom of owing to disturbance of the container is 5 said discharge pipe, a second pipe having avoided.

free outlet to the air ext'endingthrongh the bottom of the casing and the container and JAMES FLUKER.
